HARRY S. CORNISH, OF CHICAGO, ILLINOIS.

LIQUID MIXING AND DELIVERY APPARATUS.

Application filed March 6,

To all whom it may concern:

Be it known that I, HARRY S. Connrsrr, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Liquid Mixing and Delivery Apparatus, of which the following is a specification.

My invention relates more particularly to apparatus for dispensing such drinks as are compounded at the counter where they are sold, of a flavoring matteror syrup and an uncharged water or the like. It is desirable to dispense both the water and the syrup or flavor from the bottle or package in which they are received in the shop or restaurant where the beverages are dispensed. It is practically essential to provide means whereby the same proportion of syrup to water may be automatically drawn and without special care on the part of the attendant. My improved apparatus provides means whereby this desired result can be accomplished.

In the accompanying drawing and in the following specification I have described a preferred form of apparatus embodying my invention, but it i to be understood, however, that the specific disclosure is for the purpose of exemplification only and that the scope of the invention is defined in the following claims in which I have endeavored to distinguish it from the prior art as known to me, without, however, relinquishing or abandoning any portion -or feature thereof.

The drawing represents in. substantially central vertical section the preferred form of my device. The latter comprises a box or casing 1 which may be composed of outer and inner shells 2, 3, spaced apart and separated by a filling of felt I} or other suitable heat insulating material to assist in maintaining the temperature of the interior. The inner casing 3 is water-tight and within the same is mounted a separate sheet metal receptacle 5 spaced apart from the casing, as shown, a substantial uniform distance on all sides to form a continuous chamber about such receptacle for a purpose which will apear. p The receptacle 5 has divided from the main body thereof a water chamber 6, which is formed with an offset or elbow 7 having a neck 8 for a purpose which will presently appear. A cover 9 fits upon the top of the Specification of Letters Patent.

casing and is provided with a cup 10 which fits within an opening 11 in the cover and depends beneath the same where it is formed with an opening 12 which is adapted to register, when the cover is in place, with the neck 8 upon the water chamber heretofore described. The opening 12 is fittedwith a plug 13 which is centrally cored at 1 1 to form a water passage and the latter communicates by a side opening 15 with the elbow portion of the water tank or receptacle. The upper end of the hollow plug is normally closed by a valve 16, the stem 17 of which extends axially through the plug and is reciprocable therein. A float 18 within the tank 6 is pivoted through an arm 19 to the plug at 20 and at 21 is pivoted by a loose connection to the valve stem.

The cup 10 to which reference has heretofore been made is adapted to receive and support a bottle of water with its neck projecting into the cup as shown in dotted lines at 22. WVith this construction, when the water in the tank 6 falls below the desired level the float 18 drops thereby slightly raising the valve 16 permitting water to flow from the cup 10 into the tank to raise the level of the water in the latter to the normal. Vhen the level of the water in the cup 10 falls below the line of the mouth of the bottle inverted above it permitting air to enter the bottle, enough water flows from the bottle to restore the normal level of the liquid in the cup.

The tank 6 communicates with the water chamber or space surrounding the receptacle 5 through an opening 23 but preferably, in order that the more thoroughly cooled water from the bottom of the tank may fiow to the chamber surrounding the receptacle, a passage 24L communicating with the tank near its bottom, as at 25, commimicates with the opening 23, and being closed except at said opening and the bottom of the tank, insures that any water supplied to the annular water space fiows thereto from the bottom of the tank. Diametrically opposite the opening 23 a faucet 26 communicates with the annular chamber between the receptacle and the casing by means of which faucet the water from said chamber is drawn off and mixed with the syrup or flavoring matter.

The faucetccomprises a shank 27 which extends into and through the wall of the casing 1 and in its outer end is formed with a barrel28 to receive a turning plug 29 provided with a handle 30. The body of the faucet is formed with a pair of channels 31, 32, both of which communicate with the barrel, passage 32 communicating at its inner end with the annular water chamber while passage 31 at its inner end communicates through a vertical passage 33 in the wall of the casing with a cup 34 adapted to receive a bottle of syrup or flavoring in an inverted position. The turning plug 29 has a central, axial passage 35 which in one position of the plug is put into communication with the passage 31 leading tothe syrup receptacle, and an annularpassage 36 in said plug communicates in the same position with passage 32 leading tothe water supply. In normal position, however, the plug closes the passages 31, 32. In orderto adjust the relative amounts of water and flavoring syrup I provide the body of the faucet above and below with bolts 37, 38 which extend into the passages for the syrup and water respectively, and when adjusted to extend partially into said passages, choke the same and regulate the flow of liquid therethrough.

WVhen my beverage dispensing apparatus is in use the receptacle 5 is partially filled with ice surrounding the tank 6, a bottle of water with the cork withdrawn is inverted upon the cup 10 and a bottle of syrup inverted'in the cup 34. As soon as the bottle is put in place on the cup 10 the liquid flows therefrom into the cup and, the valve 16 being open, into the tank 6 until the latter is filled to the proper level when the float 18 closes the valve. In the meantime the water will rise in. the conduit 24 and overflow into the annular water chamber surrounding the receptacle bringing the water therein to the same level as that within the tank. The cup 10 then fills with water until the neck of the bottle is sealed. IVhen the bottle of syrup is inverted in the cup 34 the liquid flows therefrom until the passage 33 and cup 3a are sufliciently filled to seal the neck of the bottle. hen a glass of beverage is to be drawn it is only necessary to turn the plug of the faucet to communicate with the syrup and water passages therein when the proper mixture will flow into the glass. The flow is absolutely by gravity and as, by the con, struction described, the level of the water and that of the syrup can be maintained practically constant, the proper proportions of'the two will always be obtained. Theice immediately surrounds the water tank and the receptacle containing the ice provides a very large surface for cooling the relatively thin body of water surrounding the same and because of the'long passage from the tank to the faucet the water is thoroughly chilled before reaching the latter.
